Alzheimer’s may start shrinking two brain regions years before memory loss
Johns Hopkins scientists have uncovered hidden warning signs of Alzheimer’s disease that may appear up to a decade before memory loss begins. Brain scans revealed that two regions involved in memory and emotion start shrinking before the hippocampus, the area doctors typically examine for signs of Alzheimer’s. These early changes are linked to abnormal tau protein buildup and could provide a powerful new way to identify people at risk.

Scientists discover a bizarre paradox among endangered penguins
A groundbreaking drone survey has revealed a startling split in the fate of New Zealand's endangered Erect-crested penguins. While one population has remained stable for decades, another has declined by more than 40%, apparently due to a combination of predators, worsening storms, and changing ocean conditions. Even more surprisingly, the tiny Bounty Islands support nearly as many breeding pairs as the Antipodes Islands, despite being 40 times smaller.

Dinosaurs may have been eating seaweed 100 million years ago
Dinosaurs may have been snacking on seaweed and other ocean foods more than 100 million years ago, according to surprising new evidence hidden in their fossilized teeth. Researchers discovered chemical signatures suggesting that coastal dinosaurs and other prehistoric animals relied partly on nutrients originating in the sea. The findings reveal that marine resources traveled through ancient food chains, supplementing the diets of everything from plant-eating dinosaurs to predators.

Physicists use laser light to unlock a crystal's hidden electrical powers
Scientists have discovered how to use flashes of laser light to organize tiny electrical regions inside a crystal, solving a decades-old mystery about how the material behaves. The laser-induced alignment lasts just a trillionth of a second, but the breakthrough could open the door to new ways of processing and storing information.

Scientists find a simple daily routine linked to less pain and depression
A simple change to your daily routine could make a surprising difference in how you feel, both physically and mentally. University of Missouri researchers found that older adults who followed consistent daily schedules reported less physical pain and fewer symptoms of depression, even when they struggled with insomnia. Keeping regular times for sleeping, eating, and other activities may help regulate the body's internal clock, which influences mood, sleep, and overall health.

Yale scientists reveal what really slows aging and what doesn't
Yale researchers have discovered that certain prescription drugs, healthy diets, and exercise can measurably slow biological aging, while popular anti-aging supplements appear largely ineffective. Their analysis of 51 studies could transform how scientists evaluate anti-aging treatments, although whether these biological changes actually extend life remains uncertain.
